This was reinforced by a ruling from the ICS’s parent organisation IUGS saying that the merger was ‘on Organisers: hold’ since no formal agreement had been received from Dr Darrel Maddy (University of Newcastle) INQUA by the IUGS. Phil Gibbard emphasised that the Dr Antony Long (University of Durham) merger was certainly not the preferred option of INQUA, Dr David Bridgland (University of Durham) but that if the ICS wanted this INQUA was prepared to accept it, pending guarantees that the Quaternary would Online information and registration: be properly represented.
